This discovery isin the art of small hand tools and its concept is in advances in the constructionand operation of hand tools ofthe pliers'type.v

It is an object of this invention to provide a simple, practical,` substantialflowcost pliers tool incorporating crossed plier members each having at its opposite ends faces or jaws differentiated in such manner that the opposite' ends of the pliers can be utilized for the per formance of entirely different functions and to provide a handle device having the purpose not only of closing the jaws on or as to the given work but, further, having the function of open- 6 claims. l(cl. 81-47) ing the jaws at the respective ends of the members.

The invention consists in certain novel consame time. The disclosed means for this dual function includes ,af'pair of substantially duplicate` and completely reversible handle elements 9 andw` Il) `eachfhaving .one end hung `on a respective f .outboard pivot `lll (or l2) `in the outer endwoiw. the said block 2; these handles being turnable entirely around the ends of the block so as to take positions embracing` either en-d of the members Il and 5 as to their pivot 3. In operation, as the handles are closed toward each other they approach longitudinal, lateral ns i3 forming rigid parts of the members Il and li and which are designed to snugly slide with wedge action into complementary V-channels lll provided longitudinally in the two side faces of the handles 9 and Ill. It

i will benoticed that each member d and 5 has ceptlons in the pliers tool art as set forth in the ensuing text and having, with the above, additional objects and .advantages as hereinafter da veloped, and whose constructions, combinations and details of means and the manner of operation will be made manifest 'in the following description of the herewith illustrative embodiment; it being understood that modifications, variations, and adaptations may be resorted to within the scope, principle and spirit of the invention as it is presently claimed in the addendum.

Figure 1 is a plan, partly in section, of the tool.

Figure 2 is a cross-section on line 2 2 of Fig. 1.

Figure 3 is an end elevation of the pliers.

A suitable journal block 2 has a central pivot 3 from top to bottom and on the pivot is swingably mounted .a pair of crossed members l and 5. The opposite ends (as to the pivot 3) of these members are provided with work engaging or function-performing jaws of differentiated kinds; the jaws which are in lateral opposition on each common side of the pivot beingof paired design.

That is, directly opposite jaws are designed to cooperate functionally. Thus one end of the interpivoted members includes a pair of opposed plane faced gripping jaws 6 5 and if so desired may have opposed shears 1 1. The opposite end of the paired pliers (members 4 5) is shown as having conventional long-nose jaw parts 3 8. This jaw disclosure is but exemplary in kind as a very great range of plier faces or jaws is within the scope of the invention.

It is obvious that both ends of the pliers will open or will close at the same time as the members swing on their medial fulcrum 3; And a distinctive feature of this invention is in the novel means by which the members are either pulled open at the same time or are closed (at their opposed work `performing parts) at the such a fin i3 on each of its jaws projecting each way from the common pivot 3. Therefore in the position of the parts shown in Eig. l, the inner faces of the handles are longitudinally straddling the interposed iins I3 of the long-nose parts of the members and as the handles are closed both ends of the pliers are being closed; the outer jaws 6 6 clinching on work W. If, now, the handles are pulled apart and swung half-acircle around their pivots Il or l2 they will initially operate, by reason of frictional engagement on the ilns I3 of the jaws 8 8, to pull open both ends of the pliers at one time. During this reverse ofthe position of the levers or handles Q lt they will disengage the contact on the ns and at the other extreme of the reversing action the then inside face channels ld of the handles will ride onto the presented fins of the jaws 6 5, now in opened position, and further action of closing the handles will result in closing `both sets of jaws 6 6 and 8 8 at the same moment; in this position of the handles the long-nose jaws 8 8 are thus entirely clear from the handles and fully presented for use on any desired work.

The desired friction as between the ns and the walls of the channels (the tops and bottoms) i4 can be effected in any suitable manner. f In the instant case the i'lns are shown as longitudinally slit at l5 to permit of desired spring of the lips of the fins as they are crowded into the cooperative channels of the handles. Conversely, the lips of the channels may have the desired spring capacity.

What is claimed is: l

1. A hand pliers consisting of la pair of crossed members having at each end differentiated work engaging features, those on common ends being cooperative, a body on which the members are tiltable on a common pivot, `and a pair of handles pivoted on the tbody and swingable in half-circles to engage and close either end of the pair of members, and means disposed on the outer sides of the workl members to releasably interconnect with either of opposite sides of the handles to pull the members to open position as the handles are moved outward at either end of the pliers.

2. The plersofclaim 1; said means including mutually engaging friction parts on oppositesides1 of the handles and along the outer sides of said members.

3. The pliers of claim 1; said means including cooperative interwedging iin andchannel f-eatures==' -i along opposite sides of the handles. and along the outer sides of the said membersw 4. The pliers of claim 1; saidfmean-s including Wedge section fins on the outer sides of said members and the handles having channels along theirr11 opposite sides frictionally rengageable with the ns':

6. The pliers of claim 1; said means including wedge fins on the `outer sides of said members and cooperative Wedge channels on opposite sides of the handles yand said iins being longitudinally, inwardly channeled to increase resilient wedging reaction in the wedge channels.
